Hello,

I would like to test an Access sub form using VBA to see if it's empty. If it is, I would like to modify controls on the main form.

The sub form does not allow edits, additions, or deletions. How do I test the sub form to find out when it's empty? Also, do I use the test in the main form onCurrent event?

Thanks

Create a record set for the table or query of the subform where the link field = main form link field.
If rs.RecordCount=0 then
  'it is empty
End if

Ex:
Private Sub Command23_Click()
    Dim rs As DAO.Recordset
    Set rs = CurrentDb.OpenRecordset("Select * from tblY where M= " & Me!M)
    If rs.RecordCount = 0 Then
        MsgBox ("Subform is empty")
   End If
End Sub
       
    rs.Close
